The correct answer is B. connotation.
Connotation refers to your emotions and attitudes when it comes to a particular word. For example, when you say the word 'home,' you will probably have positive emotions when you think about your family, warmth, and hot meals. Denotation is the actual definition of a word you would find in a dictionary (so it is the same as option A), and origin of the word has nothing to do with feelings.
